HANDLE-BAR FOR BICYCLES, 800.

SPECIFICATION forming part of Letters Patent No. 650,963, dated June 5, 1900. Application filed Dtceinher 4, 1899. Serial No. 789,176. (No model.)

To all whom, it may concern:

Be it known that I, ELWIN J. BABBITT, a citizen of the United States, residing at Petoskey, in the county of Emmet, State of Michigan, have invented a certain new and useful Improvement in Handle-Bars for Bicycles, &c., of which the following is a specification, reference being bad to the accompanying drawings.

This invention relates to an improvement in adjustable handle-bars for bicycles and like vehicles, and has for its object a means of attachment of the handle-bar proper whereby the latter may be adjusted forwardly and downwardly or rearwardly and upwardly by one movement of the said bar. It has heretofore been the practice to accomplish this object by two separate movements, and my invention is designed to obviate one of them.

Vith this main object in view my invention consists in the peculiar construction, arrangement, and combination of parts hereinafter described, and then definitely claimed at the end hereof.

In the drawings accompanying this application, and which represent the preferred form of my invention, Figure 1' is a perspective view of a bicycle-head having my invention applied thereto. Fig. 2 is a vertical central section. Fig. 3 is a top plan, and Fig. 4 is a perspective view, of the fastening-clamp and a modified form of tightening the same.

Fig. 5 is a detail with the locking device re-' moved. Fig. 6 is a section through the line w x on Fig. 2.

Referring now to the details of the drawings by letters, A represents the head of a bicycle of any desired construction, which is shown merely to illustrate the means of using my improvement. 7

B represents a tube or stem, preferably adjustably secured in said head by the bolt and nut 19 b. Projecting downwardly from this tube or stem B, and preferably integrally secured thereto at an acute angle, is the tube 0, closed at its lower end by any desired means. This tube is flattened on its under side, so as to be substantially D -shaped in cross-section, and slidingly secured to this D-shaped or flattened tube is the handle-bar clamp E, made, preferably, in the form of a tube cut away on its under side, as shown at (2, so as to allow the clamp to slide completely up to the top of the main stem B. This tubular clampis likewise flattened to correspond with the flattened tube and to prevent its turning thereon. (See Fig. 6.)

Two arms F F project from the clamp and form a means of supporting the handle-bar G, which may be of any shape, but is preferably bent inwardly at g and secured to the tubular part of the clamp, as shown in Fig. 1. The lower part of the clamp E is split at 6, so as to allow of its being fastened on the tube 0, and two perforated ears or lugs H H project from the clamp over the split portion e and are provided with a bolt passing through the perforations, and on the outer end of this bolt is securely fixed a collar or nut It. Between this collar h and one of the ears H works a lever I, which is threaded on the bolt and is designed, when moved in one direction, to. screw against the ears, and thus secure the clamp on the tube, and when moved in the opposite direction to move away from the ears, and thus release the clamp, so that it can be moved on the tube If preferred, the collar or nut it may be loosely fastened on the bolt by riveting or upsetting the end of the latter and a coiled spring h (see Fig. 5) secured over the bolt between the lever I and said collar or nut to prevent the latter from rattling.

It is obvious thatinstead of making the ears, integral with the clamp a separate band J may be provided, as shown in Fig. 4, and that in place of the lover I a wing nut or a nut panying drawings it is seen that if the handle-bar is at the upper end of its movement the rider may adjust it both downwardly and forwardly by turning the lever I and, if he wishes, without leaving his saddle, and when it is moved upwardly the handle-bars simultaneously move rearwardly, this forward or rearward movement being dueto the angle at which the tube 0 is connected to the main tube or stem B.

It is evident that the tube 0 may beconnected to the main stem B at a different ana handle-bar, means for adjusting said clamp and its arms, and a handle-bar secured in said projecting arms and movable with said arms and their clamp, substantially as described.

In testimony whereof I affix my signature, in the presence of two witnesses, this 2d day of December, 1899.

ELWIN J. BABBITT.
